摘要

[Problem] To provide a method for producing a substituted 4,4-difluoro-2-buten-1-one compound and a method for producing a substituted isoxazoline compound. [Solution] A method for producing a substituted 4,4-difluoro-2-buten-1-one compound represented by general formula (1) from a compound represented by general formula (2) by carrying out a dehydration reaction in the presence of a phase transfer catalyst. A method for producing a compound represented by general formula (1) from a compound represented by general formula (3) and a compound represented by general formula (4) by carrying out a condensation and dehydration reaction in the presence of a phase transfer catalyst. A method for producing a substituted isoxazoline compound represented by general formula (5) by adding a hydroxylamine compound after the processes for producing a compound represented by general formula (1).
